sartorial (adj.) "pertaining to a tailor," 1823, from Modern Latin sartorius, from Late Latin sartor "tailor," literally "patcher, mender," from Latin sart-, pp. stem of sarcire "to patch, mend." Sartorius as the name of the long leg muscle is because it is used in crossing the legs to bring them into the position needed to sit like a tailor.

Sometimes I marvel at my ignorance. When two words are put together, they sometimes meld into one meaning that exceeds either of the two; sort of a verbal synergism. I knew the meaning of sartorial and splendor. I guessed at the words sartorial splendor and missed the mark. Ignoring the meaning of sartorial in its solo setting, I assumed I was reading celestial splendor. Were it not for Gail, I would still be basking in my ignorance. The alliteration goes a long way toward creating the beauty of this expression.
